Rsync builds the list of files first, *then* transfers them.

Thus, the case to worry about is if it transfers db/current *after*
another commit has occurred during the rsync (and the newly created
revision file is thus not in rsync's list of files), and then you have a
db/current that refers to something that wasn't transferred.

Hence the reason to transfer it first.
